Wigan: Left-back Leighton Baines is a major doubt after injuring a hip in last week's 1-0 defeat to Middlesbrough. David Unsworth, signed on a free transfer from the Blades in January, is poised to step in. Latics captain Arjan de Zeeuw (ankle) is also a doubt having missed the Boro game. Squad: Pollitt, Taylor, Boyce, Scharner, Baines, Unsworth, Valencia, Landzaat, Skoko, McCulloch, Heskey, Aghahowa, Folan, Filan, Kilbane.
